To all lwhom it may concern:

Beit known that we, GORYDON WHEAT and ALFRED OA'rcHPoLE, both of Geneva,Ontario4 county, New York, have invented a certain new and usefulImprovement in Heating-Appara-A tus; and we do hereby declare that thefollowing is a full, clear, and exact description of the same,refercncebeing had to the accompanying drawings, in which- Figure 1 is a centralvertical section of a boiler, showing our improvement. Fig. 2 is asimilar View at right angles to Fig. l. Fig. 3 is a section of one sideofthe upper portion of the apparatus, showing more particularly themeans for extending the height of theniagazine. Fig. et is a plan viewof the lower sec- Fig. 5 is a plan of one of the upper sectional ringsD. Fig. 6 is a horizontal section of one of the upper rings D, enlarged.Figs. 7 and 8 are cross-sections of one of the rings D respectively inlines :v and y y of Figs.

5 and 6. Figs. 9 and l0 are detail views, showing the registers andslides. Fig. 11 is a bottom view ofthe dome. Fig. 12 is an elevation oftwo-of the rings D, exhibiting the notches therein for admitting thetubular door.

This improvement relates to steam-heating apparatus.

'lne objects sought in the invention are simplicity and cheapness ofconstruction, safety against over -pressure, due to the form of thesectional rings, convenience of transportation, and ability to build upboilers of varying sizes with great facility and ease, either instationary or portable form. i

The invention consists in the construction and arrangement of partshereinaftermore definitely described and claimed.

In the drawings, A shows a base, forming the support for ,the sectionaltubular rings, and having a grate, B, of ordinary form.

(l is a hollow tubular ring,which rests upon this base, the passagethrough the ring being unobstructed, j and said ring having two or moreopen-topped bulbs or enlargements, a a, Fig. 4, which allow the water topass into the upper rings, which are of larger diameter.

D D are the upper sectional tubular rings, of which any desired numbermay be used, according to the size of boiler it is necessary to make.These rings are simply laid one on top of another, with suitableattaching devices for holding them firmly together.` Each of the rings Dis constructed as follows: It is made i hollow for the free passage ofwater. It may be made of any desired form, both in outline and crosssection; preferably, however, the rings are square in cross-section, tofacilitate casting and to fit better in building up. On opposite sidesare ports or passages b b, Fig. 5, which fit over the bulbs a 'a of thelower ring, O, and which fit over each other in the successive sections,so as to make a connected passage on the two opposite sides clear up tothe top of the boiler. The ring is also provided with a series ofopen-ended Hue-tubes c c, arranged around the whole circumference, andwhen the rings are built up one on top of another these flue-tubes allcome in line and make connected passage-ways from bottom to top, asshown in Fig. 2. At the bottom they open ontside the lower base-ring, C,which is of smaller diameter than the other rings, and at the top theyopen into a space, d, communicating with the nre-chamber E.

F is a hollow ,domesection, which its on top ofthe upper ring D, and hasports corresponding with the ports b b, by which the hot Water isallowed to enter the dome. It has also a downwardly -projecting Bange,e, which restsv on top of the upper ring, thereby forming the fire-spaced, before described. It has likewise tubular passages ff, covered byStoppers g g, through which a poker, brush, or rod may be inserted intothe flues c c, for the purpose of cleaning the latter from soot andashes. The parts thus constructed are all bolted together by bolts or"rods h h, which extend down from the dome through the ports b b, and aresecured in place by nuts. The ports b b are divided centrally andvertically by partitions or webs it', which extend to and join with theadjacent ends of the two ues c c next to them, but extend no farther, sothat the ues c c beyond aredisconnected from each other and the watercan'ow freely around and between them. The partitions all coincide, andtheir ends meet, making thereby passage-ways from top to bottom. Thedome F has the samepartitions i z',- but they are cleft or slotted inthe center, as shown in the bottom view, Fig. 1l. By the means of thesepartitions t i a double passage- IOO way is made from topto bottom, andthe hot cool water will descend the outer passage, thus i making acircuit, as indicated by the arrows, Fig. 7. In addition to this thepartitions it' form posts or piers to strengthen the rings and preventany crushing or springing of the rings under pressure.

G is an open-ended ring or cylinder, which rests on topot' the dome, andwhich we denomi- -nate the smoke-stack,since it has a smokepipe, H',extendingt'rom its back and opening into the main smoke-pipe H. On topof this ring rests the flange;` of acylinder, I, ot'smaller diameter,which rests within and extends through the ring, and has attached at itslower end the magazine J. The cylinder I has in its sides and nearthetop a series of small holes, s2 s2, which open outward into the spacebei tween the cylinderand the ring G,and form passages for the escapeot' gas from the top of the magazine into said space, whence it escapesthrough pipe H' into the main smoke-pipe H. By this means a free escapeof gas is allowed and all danger of explosion is obviated.

The magazine is made of a series of overlapping rings, 7c la, formingsections that can be applied or removed at any time to make the magazinelonger or shorter to correspond to the height to which the boilerisbuilt up. The cylinder I rests between projecting lugs l l in the eyeofthe dome, which center the cylinder and leave a circular space, m,through which the smoke and products of combustion can pass from thefire-chamber to the exit-pipe H' inthe ring G. On the angej of thecylinder I is a groove, a, in which tits the edge of the cover L, asshown in Fig. 2; or, in case it is desired to build the magazine higher,one or morerings, M, may be placed on the top of the cylinder I, and thecover be placed on -top ot' the Lipper ring, as shown in Fig. I. Thegrooves in which the edges rest are lled with sand to form a packing.and prevent the escape ofgas. Byr this construction it will be seen thatthe Y magazine and its connections are portable and can be removed andreplaced withoutdifficulty, and, furthermore, the magazine is supportedand retained in place by the ring G, and not by the boiler. In thismanner the capacity ofthe magazine maybe increased at pleasure.

N is ajacket or casing, surrounding the Sectional rings and connectingthe base with the dome, and leaving a thin space between itself and therings, which simply forms a iiue for the escape of the products ofcombustion.

0 c, Fig. 5, are flanges forming partitions, which stand radially andvertically up and down between this'jacket and the rings D D, and dividethe annular Iiue space into as many different and separate nues p p asthere are anges. These anges come on a line between the iues c c ofthe'rings D D, so that the flue-spaces p p each comes opposite andcovers one of the iiues c c, thereby imparting the maximum of heat tothe water, which lies in a thin body between the two nues. These angeso0 keep the heat from circling around indefinitely, and coniine the heatto straight currents covering the dues o 0. The flanges o 0 extend fromthe bottom of the lower ring D to the top ot' the upper one,their.lengththerefore being exactly the vertical height of the rings D D, andleaving the spaces above and below the rings open and unobstructed.

I is an exterior casing or jacket, extending from the base to a littledistance above the dome, where it is carried in and strikes the ring G,thereby forming a jacket-space around the inner casing, N. Cold air islet in at the bottom of the exterior jacket-space and is passed out atthe top through a pipe or pipes, and may be used to heat outside rooms.The exterior jacket serves to prevent the passage ot' heat outward, thusserving as a shield. If

desired, it may be dispensed with entir`ely.`

Slides or covers t' r are made in both the outside and inside casings toallow entrance to the space around the rings for the purpose of clearingthe same ot' ashes and soot, which are swept out through holes providedwith stoppers s s, as shown in Fig. l.

H2 is a branch of the smoke-pipe, which passes in and connects with theinner Huespace between the inner jacket and the rings. Both of thesmoke-pipe branches H H2 have dampers u u, by which the draft can becontrolled. -l

e is a sliding register on the fiange e of the dome F, coveringopeningsthrough said flan ge. By moving the register' in one direction the draftfrom the nre-chamber will pass through the openings, and by moving it inthe other direction the draft will be cut off. This is ot' servicesometimes where it is desired to produce a draft less intense than thatthrough pipe H and more intense than that through pipe H2. The register@is on the opposite side from the smoke-pipes, and the draft therefromhas to make a half-circuit before it reaches the smoke-pipe H2, where itescapes.

R is a circular tubular door, set into the boiler through the casingsand the rings, and reaching to the fire-chamber E, as shown in Fig. 2,by which means the tire may be reached at any time. The outer end iscovered by a door or nap', w.. To allow the inner end ofthe lube to passthrough the rings DD, two of said rings have openings or notches t tmade therein, as shown in Fig. 12, the notch in each extending one-halfthe width of the ring, but leaving a free passage-way for the waterabovethe notch, so that the water can circulate throughout the whole ring,thereby preserving uniformity in the expansion of the ring under heat.The tube It enters the opening thus made and makes a clear passage fromthe outside of the boiler to the tire.

S is the piping which' leads oft' from the top of the boiler through.the building to be heated, and T is the return-pipe, arrnn ged in theordinary way.

VFrom the above description the operation will be readily understood.The water as it becomes heated in the rings rises through the.innerpassages to the top` and then descends IOO IOS

IIS

through the outer pasages, thus making a constant circulation.4 It alsospreads and circulates throughout each ring, and in coming in contactwith the dues c c it receives additional heat. In kindling or startingthe tire, the valve u in vsmoke-pipe H is opened, which allows a directdraft upward, the draft passing through the circular space m. When there is properly established this valve is closed and the valve in pipe H2is opened. The draft then passes up through the hre-chamber over the topofthe rings; thencepasses down through the uesc 0,-aud thence passes upagain through the lines 1J p, between the jacket 'N and the rings, andtinally escapes, the heat thus snrrounding both the inner and outersides of the rings also passing through the center, obtaining the besteffect of the heat. By making the lower ring, U, ot' smaller diameterthan the others, a space is left around the bottom which allows thedraft to turn and circulate, and also gives room to clear out ashes andsoot. The damper v allows an intermediate draft between the direct andindirect when desired.

The dome F is of peculiar construction. It is hollow and receives steamand water through ports lcommunicating with the ringsbelow.

It has a central eye or opening, through which the ring passes whichsupports the magazine. It has a vertical dan gc or skirting, which restsupon the upper ring and forms a tire space at the top ofthe re-ohamber,and it has an inclined bottom, which allows water to stand thereon-whenthe dome is dry.l thereby obviating cracking ofthe same under heat.

Havingthus described our invention, we claim- 1. In a heating apparatusconsisting of a series of hollow watersections placed one u pon another,the bottom section, C, of less diameter than the upper sections, D, andcommunicating therewith by ports a a, the uppersections off setting orprojecting beyond the bottom section, leaving a space in the bottom ot'the boiler, into which the dues c c of the upper sections open, and `inwhich are located the stoppers s s, asl'herein shown and described.

2. In a heating apparatus, theA hollow ring or section I), constructedwith the ports or openings b b on opposite sides, forming waterways, thevertical partitions t', dividing said ports, andthe tlues c c, extendingvertically through the ring, allin combination, as shown and described,and for the purpose specified. 3. In a heating apparatus, thecombination of the several water rings orsections D D, placed one on topot' another, forming :a stack, said rings provided on opposite sideswith ports b b, divided vertically by partitions t' t, forming distinctwater-channels from bottom to top of the rings, and provided with lues cc, forming draft-passages through the rings, as and for the purposespecified.

4. In a heating apparatus, the combinatio i of the dome F, having acentral eye or opening, the separate ring Gr, resting on top ofthe dome,surrounding the eye or opening, and provided withan exit-pipe, H,whichcommunicates with the main eXit-pipe,`and a loose cylinder, I, rest-ingon top of thering Gr, eX- tending down through the dome, forming anattachment for the magazine, and havingin its sides near the top aseries of small holes, s2 s?,

for the escape of gas from the magazine into t 6.- In a steam-heatingboiler, the combination, with the sectional rings D D and the casing N,of the radial anges or partitions o o, resting between the rings and theeasing, said flanges extending from bottom to top of the series ofrings, and forming iiues pp, which come opposite the ues c c of therings, as,

herein shown and described.
